What Travellers Say
Reviews Summary
Visitors are captivated by the magical views and the engineering marvel of the Kahuish Tunnel, one of the world's highest. The surrounding natural beauty, including Querococha Lagoon and its unique geological fault, adds to the allure. However, the extreme altitude poses a significant risk of sickness, and drivers must exercise caution due to poor visibility and sharp curves.
"Before and after entering the tunnel the views are magical... nature, its fauna, its flora are now all green around... I arrived early around 11 am, but from 1 pm the hailstorm and rain started... be careful... beautiful photos of the surroundings will come out... if you go through the tunnel use all your lights and honk your horn, I am already used to the mountains, that's why the altitude sickness doesn't bother me, but I saw several people fainted..."

"A unique spot, the tunnel that connects the Callejón de Huaylas and the Conchucos area, 4,516 meters above sea level, 900 meters long. If you visit this area, you'll find Querococha Lagoon on the route, a must-see. Also, look closely to the right side of the lagoon; you'll see a geological fault shaped like the map of Peru. And don't forget to visit the Chavín de Huantar archaeological complex."

"This tunnel is the ABRA or highest point to cross the mountain range on the way to Chavín de Huántar. Be careful because there is a curve just as you exit. Its location will be mentioned by the guides at the archaeological complex."
